Heat shrink wrap for pipes

Numerous boxes of rubber material and chemicals that you would use to wrap and insulate pipes...really, this is for big pipes, or commercial use, not little tiny pipes. It's about a pallet and a half worth of stuff. It's a lot. My husband got this at an auction thinking it was something he could use for electrical connections, but, yeah, now it is taking up a lot of space, and can someone make us an offer and put this stuff to use and get rid of it. I would like to reclaim the area of cement it is taking up. I will try to get a picture of it, but it's a bunch of boxes and black rubber stuff.
